+Fixes server-rendered routes returning 404 errors
+
+A configuration error in the build output prevented Netlify from correctly routing requests to server-rendered pages, causing them to return 404 errors. This fix ensures that all server routes are properly handled by the Netlify SSR function.

 # astro
 
+## 6.0.0-beta.17
+
+### Minor Changes
+
+- [#15495](https://github.com/withastro/astro/pull/15495) [`5b99e90`](https://github.com/withastro/astro/commit/5b99e9077a92602f1e46e9b6eb9094bcd00c640e) Thanks [@leekeh](https://github.com/leekeh)! - Adds a new `middlewareMode` adapter feature to replace the previous `edgeMiddleware` option.
+
+  This feature only impacts adapter authors. If your adapter supports `edgeMiddleware`, you should upgrade to the new `middlewareMode` option to specify the middleware mode for your adapter as soon as possible. The `edgeMiddleware` feature is deprecated and will be removed in a future major release.
+
+  ```diff
+  export default function createIntegration() {
+    return {
+      name: '@example/my-adapter',
+      hooks: {
+        'astro:config:done': ({ setAdapter }) => {
+          setAdapter({
+            name: '@example/my-adapter',
+            serverEntrypoint: '@example/my-adapter/server.js',
+            adapterFeatures: {
+  -            edgeMiddleware: true
+  +            middlewareMode: 'edge'
+            }
+          });
+        },
+      },
+    };
+  }
+  ```
+
+### Patch Changes
+
+- [#15657](https://github.com/withastro/astro/pull/15657) [`cb625b6`](https://github.com/withastro/astro/commit/cb625b62596582047ec8cc4256960cc11804e931) Thanks [@qzio](https://github.com/qzio)! - Adds a new `security.actionBodySizeLimit` option to configure the maximum size of Astro Actions request bodies.
+
+  This lets you increase the default 1 MB limit when your actions need to accept larger payloads. For example, actions that handle file uploads or large JSON payloads can now opt in to a higher limit.
+
+  If you do not set this option, Astro continues to enforce the 1 MB default to help prevent abuse.
+
+  ```js
+  // astro.config.mjs
+  export default defineConfig({
+    security: {
+      actionBodySizeLimit: 10 * 1024 * 1024, // set to 10 MB
+    },
+  });
+  ```
